What is Ultrasonic […] A jig is defined as a device which (A) Holds and locates a workpiece and guides and controls one or more cutting tools (B) Holds and locates a workpiece during an inspection or for a manufacturing operation (C) Is used to check the accuracy of workpiece (D) All of the above This is basic of water jet machining (WJM). Ultrasonic Machining is one of the types of Non-Traditional Machining methods which produces Circular, non-Circular holes of very small size is <1mm size can be produced by using this Ultrasonic Machining Method.. The following of Ultrasonic Machining application are: Ultrasonic Machining is used for the Machining of non-conductive ceramics. This is how ultrasonic machining works. If necessary, a slurry containing carborundum grit may be used; diamond tools can also be used. D.C. supply is usually obtained from generators driven by electric motor or if no electricity is available then the diesel engine can be used. 1. c) 0.5 μm Profiling the holes. View Answer, 4. Working Principle of ultrasonic Machining: Let us know if you liked the post. On which of the following features of cavity, will the penetration depth depend on? Economic considerations and recent developments in USM Economic considerations: The process has the advantages of machining hard and brittle materials to complex shapes with good accuracy and … a) Depth The device for converting any type of energy into ultrasonic waves is the ultrasonic transducer. Ultrasonic Machining Process description. The solved questions answers in this Unconventional Machining Process - 1 quiz give you a … In order to cut harder materials like metals or granite, an abrasive material is mixed in the water. View Answer, 3. a) True b) False ... here is complete set of 1000+ Multiple Choice Questions and Answers. Which results in faster machining, however, it is seldom used because of … b) <500 mm2 This machines having great properties like: Ultrasonic machining is Mechanical machining methods. The Ultrasonic Machine consists of different parts as follows: To starts, the machining process power is required.
